Waves
A disturbance that transfers energy from one place to another without transferring matter.
What is a wave?
The units for amplitude.
What is meters?
The distance between a point on one wave and the identical point on the next wave.
What is wavelength?
The units for frquency.
What is Hertz?
The highest point of a transverse wave.
What is a crest?
The type of wave that requires matter to travel through.
What is a mechanical wave?
The maximum distance a wave moves from its rest position.
What is amplitude?
The 2 easiest points on a line to use to measure wavelength.
What are crest and trough?
The number of times a wave repeats in a specified amount of time, usually 1 second.
What is frequency?
The lowest point of a transverse wave.
What is a trough?
Matter that a wave travels through.
What is a medium?
As this increases, the amplitude of a wave will increase.
What is energy?
Wavelength does not affect this property of sound.
What is loudness?
As the frequency of a wave increases, the wavelength does this.
What is gets longer or increases?
What is the rest position?
The disturbance and particles of this wave type move perpendicular to the direction the wave travels.
What is a transverse wave?
How you perceive the energy of a sound wave.
What is loudness?
A high pitched sound will have either a shorter or longer wave length when compared to a low pitched sound.
What is shorter?
The perception of high or low sounds caused by a waves frequency.
What is pitch?
The 2 parts of a wave that are measured in distance.
What are amplitude and wavelength?
The disturbance and particles of this wave type move parallel to the direction the wave travels. Sound waves are an example.
What is a longitudinal wave?
The amount of sound energy that passes through a square meter of space in one second, otherwise known as _______, decreases as sound waves spread out.
What is intensity?
This type of waves wavelength is measured from the middle of one compression to the middle of the next compression.
What is a longitudinal wave?
An instrument that plays at a frequency of 266 Hz has a lower _________ when compared to another identical instrument plays at a frequency of 400 Hz.
What is pitch?
This is half the distance between a crest and a trough.
What is amplitude?
